Flow has dropped to 70.4 CFS (gauge height 0.85 ft) at Rainbow Springs — down significantly from last week's 99 CFS and firmly in low, clear-water territory that demands precise presentations and fine tippet. Expect morning fog to burn off by 9 AM ahead of a partly sunny day with a high near 80°F and a 40% chance of afternoon thunderstorms.

Best Time Window
- 6:30 AM - 9:00 AM: Fog-shrouded midge and early BWO window — fish slow pools and tailouts with small nymphs and emergers before the sun hits the water.
- 10:00 AM - 1:00 PM: Prime BWO hatch period as fog burns off — look for rising fish in the flat glides and fish dry emergers and parachute patterns in the surface film.
- 4:30 PM - 7:00 PM: Evening caddis and terrestrial activity peaks — skitter caddis dries through riffles and drop ant patterns along shaded banks before any approaching storms shut things down.
Guide's Tip
From the benchAt 70 CFS the Nantahala is running gin-clear, so stealth is everything — stay low, wade slowly, and approach pools from downstream. Drop to 6X fluorocarbon tippet for your dry and nymph presentations, and keep your leader long (12-14 feet) to keep the fly line well away from spooky fish. Watch the sky closely after noon: if those afternoon thunderstorms fire early, the brief bump in turbidity can switch on the big browns in the deeper pools — have a sculpin or streamer ready to swing through the dark water before the storm passes.
